In the grid below, each number can be obtained through the sum of the two numbers connected directly below it. For instance, in

the last row, the 5 is the sum of the two numbers below it, 2 and 3. Using the same method, all the numbers starting from the bottom row sums all the way up to the final square, 2x. Determine the value of x if the number in the topmost square is double unknown number in the bottom row.

Answer:

x = -12.

Step-by-step explanation:

Number in the square next to  5 =  3+x.

Number to the right of this one = x + 1

From left to right the umbers in the second row = 5 + 3 + x

and 3 + x + x + 1

= x + 8 and 2x + 4.

So x + 8 + 2x + 4 = 2x

so 3x + 12 = 2x

x + 12 = 0

x = -12.

Gnesinka [82]

Answer:

b³

The lowest common multiple of the expression is b². This because, taking out a factor of b, b ( b² + 6b ), taking out a factor of b², b² ( b + 6 ),

taking out a factor of ( b + 6 ), ( b + 6 ) b². As a result b² is only the option which is not a factor.

in a certain pentagon, the interior angles are a,b,c,d,e where a,b,c,d,e are integers strictly less than 180. ("Strictly less th
guajiro [1.7K]

Answer:

  least to greatest: {61, 61, 61, 178, 179}

Step-by-step explanation:

If the third-largest angle is 61°, the smallest three angles cannot be larger than 183°. Since the total of all angles must be 540°, and the total of the largest two cannot be greater than 179°×2 = 358°, the sum of the smallest three must be at least 540° -358° = 182°.

So, the possible sets of angles with the smallest 3 totaling 182° or 183° are (in degrees) ...

  {60, 61, 61, 179, 179} . . . . two modes

  (61, 61, 61, 178, 179} . . . . . one mode -- the set you're looking for
